Personally I think you should learn how to drink beer, but that's just me. Cold mugs chill up when a cold beer is added and then you have a frozen iceberg hockey puck floating on top that melts and then waters down your beer.. but to each their own. The beer is cold enough as it is.
They just don't like you :p This is the lewisville location..
Certainly no reason I'm aware of, perhaps send the beer back, gently requesting a cold mug again.
You should probably ask the Colleyville location.
